Preparing a Good Foundation for Your New Hot Tub or Spa

September 01, 2010

Your spa needs a solid and level foundation

The area that it sits on must be able to support the weight of the spa and the occupants who use it. If the foundation is inadequate, it may shift or settle after the spa is in place, causing stress that could DAMAGE YOUR SPA SHELL AND FINISH.

NOTE: Damage caused by inadequate or improper foundation support is not covered by the warranty. It is the responsibility of the spa owner to provide a proper foundation for the spa. Place the spa on an elevated foundation (preferably a 3” concrete slab). If you are installing the spa indoors, pay close attention to the flooring beneath it. Choose flooring that won’t be spoiled or stained. If you are installing your spa on an elevated wood deck or other structure, it is highly recommended that you consult a structural engineer or contractor to ensure the structure will support the weight of 150 pounds per square foot.

To properly identify the weight of your new Spa when full, remember water weighs 8.33 lbs. per gallon. For example, an average 8’ Atlantic spa holds approximately 500 gallons of water. Using this formula, you will find that the weight of the water alone is 4,165 Lbs. Combined with the dry weight of the spa you will note that this spa will weigh approximately 5,000 Lbs. when full of water.

Note: It is strongly recommended that a qualified, licensed contractor prepare the foundation for your spa. Your retailer can help you with your foundation and more. Your retailer has a wealth of information and experience about how to get the most out of your spa and can provide you with a full line of accessories that are designed to compliment your spa and increase your enjoyment.
